IMPROVEMENT IN HEATING-STOVES.

Specification forming part of Letters Patent No. 197,644, dated November27, 1877 application filed May 21, 1877. v

To all whom 'it may concern:

Be it known that I, FREDERICK D. LIVER- MORE, of Rochester, in thecounty Of Olmsted and State of Minnesota, have invented certainImprovements in Heating-Stoves, of which the 'following is aspecification:

My invention relates to that class of heating-stoves having air-finesthrough them from top to bottom, which are made with a sheetmetal bodyand a cast-metal top and base; and the invention consists in a base Ofpeculiar form cast complete with the air-flues therein;

in the use of internal sheet-metal Ilues, in lcombination with the topand bottom, adapted to receive them, and in casting the top withconverging ilues, as hereinafter described.

Figure l represents a perspective view of my stove; Fig. 2, aperspective view of the base; Fig. 3, a vertical central section throughthe stove; Fig. 4, a vertical central section representing the top withits converging ues.

A represents the cast-metal base; 4B, the sheet-metal body 5 and G, thecast-metal top. The base is cast complete in about the usual form, witha contracted bottom to serve as a lire-pot; but, unlike those hithertoin use, it has four vertical lues, a, the lower ends of which protrudeon the outside, and have their mouths open to receiveair, while theirupper ends terminate inside of the bottom and are recessed to receivethe lower ends of sheetmetal Ilues b, one of which is seated in each ofthem, as shown.

Upon the base A, which is shouldered to rei adapted to receive and forma continuation of the lues b.

The ues c may be arranged to open separately and directly through thetopplate; but

it is preferred tO extend them across the under side of the same, andmerge them at the center in a single iiue, as shown in Fig. 4. i

By extending the ues upward through the interior of the stove intheInanner shown a very large heating-surface is obtained, and by thepeculiar construction of the parts the cost of manufacture is renderedvery low.

I am aware that stoves have been provided with air-Ilues passing throughthem. from top to bottom, and that cast-iron bases and tops have beencombined with sheet-iron bodies, and I make no claim broadly thereto;but

The combination of the base A, cast with the lues a therein,the Ilues band bodyB, of sheet metal, and the top C, cast with the ues c therein,and applied as shown.
